Abstract
Provided is a manufacturing device and a manufacturing method for a rotor core that can prevent damage from being caused to an end of a magnet due to movement of the magnet when injecting a resin material. Included are a first mold including a fitting recess that fits and holds a laminated iron core in which a magnet is inserted into a magnet insertion hole, a second mold that is engaged with the first mold and clamps and seals the laminated iron core together with the first mold, a resin injection unit that is provided to the second mold, and injects a resin material into the magnet insertion hole, and a magnet positioning and holding mechanism that positions and holds the magnet in a state of being fit into the fitting recess of the first mold.
